/**
* Takes two phone numbers and compares them for equality.
*
* <p>Returns EXACT_MATCH if the country_code, NSN, presence of a leading zero for Italian numbers
* and any extension present are the same.
* Returns NSN_MATCH if either or both has no region specified, and the NSNs and extensions are
* the same.
* Returns SHORT_NSN_MATCH if either or both has no region specified, or the region specified is
* the same, and one NSN could be a shorter version of the other number. This includes the case
* where one has an extension specified, and the other does not.
* Returns NO_MATCH otherwise.
* For example, the numbers +1 345 657 1234 and 657 1234 are a SHORT_NSN_MATCH.
* The numbers +1 345 657 1234 and 345 657 are a NO_MATCH.
*
* @param firstNumberIn first number to compare
* @param secondNumberIn second number to compare
*
* @return NO_MATCH, SHORT_NSN_MATCH, NSN_MATCH or EXACT_MATCH depending on the level of equality
* of the two numbers, described in the method definition.

*
* <pre>
* PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
* PhoneNumber number = phoneUtil.parse("18002530000", "US");
* String nationalSignificantNumber = phoneUtil.getNationalSignificantNumber(number);
